we designed password based door locking system using microcontroller 8051.interfacing of keypad and lcd screen is reqired for input and display.here we interface 3*3 keypad with microconntroller.we also provide a facility to change password....

In this competitive world human cannot spare his time to perform his daily activities manually without any fail. The most important thing he forgets to switch off lights wherever not required. With this, even the power will be wasted up to some extent. This project gives the best solution for e...

LQR control method to achieve the balancing robot balancing effect analysis of Q-value to determine best contribute to the k-value. Requires three angle control for balancing robot, robot body angle, wheel forward, horizontally transmitted and control end through the three corners to achieve...

This code is written by me for interfacing TC72 Temperature sensor with 8051 microcontroller.As 8051 microcontroller not having inbuilt SPI so I have written simulated code for SPI for 8051.TC72 is a digital temperature sensor with .25 degree resolution.
I also attached proteus simulation desi...

This is an example of controlling 3 (three) of 7 Segment common cathode using 89S52 MC. I used this to learn how to control more than one of 7 Segment using as minimum as possible to save price for large project. Well this is just an init ( I used later for queue machine of banks and any other...

If you’re a computer geek, you might think I’m claiming to have built a project that decrypts the RC5 block cipher. I wish that were the case, and indeed if it were I’d certainly be earning a lot more money than I am now! But alas, this project refers to a much simpler idea – the RC5 pr...

This is the code for password protected secure door using8051. The project consists of stepper motor, lcd, buzzer and keypad. on pressing the password which is displayed as * on lcd, 8051 checks for correct password ,if the password is correct, the stepper motor rotates clockwise to ope...
